  • EAGLView orientation changes and strange buffering

    - by Drew
    I'm writing an app that offloads some heavy drawing into an EAGLView, and it does some lightweight stuff in UIKit on top. It seems that the GL render during an orientation change is cached somewhere, and I can't figure out how to get access to it. Specifically: After an orientation change, calling glClear(GL_COLOR_BUFFER_BIT) isn't enough to clear the GL display (drawing is cached somewhere?) How can I clear this cache? After an orientation change, glReadPixel() can no longer access pixels drawn before the orientation change. How can I get access to where this is stored?

  • Strange iPhone memory leak in xml parser

    - by Chris
    Update: I edited the code, but the problem persists... Hi everyone, this is my first post here - I found this place a great ressource for solving many of my questions. Normally I try my best to fix anything on my own but this time I really have no idea what goes wrong, so I hope someone can help me out. I am building an iPhone app that parses a couple of xml files using TouchXML. I have a class XMLParser, which takes care of downloading and parsing the results. I am getting memory leaks when I parse an xml file more than once with the same instance of XMLParser. Here is one of the parsing snippets (just the relevant part): for(int counter = 0; counter < [item childCount]; counter++) { CXMLNode *child = [item childAtIndex:counter]; if([[child name] isEqualToString:@"PRODUCT"]) { NSMutableDictionary *product = [[NSMutableDictionary alloc] init]; for(int j = 0; j < [child childCount]; j++) { CXMLNode *grandchild = [child childAtIndex:j]; if([[grandchild stringValue] length] > 1) { NSString *trimmedString = [[grandchild stringValue] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; [product setObject:trimmedString forKey:[grandchild name]]; } } // Add product to current category array switch (categoryId) { case 0: [self.mobil addObject: product]; break; case 1: [self.allgemein addObject: product]; break; case 2: [self.besitzeIch addObject: product]; break; case 3: [self.willIch addObject: product]; break; default: break; } [product release]; } } The first time, I parse the xml no leak shows up in instruments, the next time I do so, I got a lot of leaks (NSCFString / NSCFDictionary). Instruments points me to this part inside CXMLNode.m, when I dig into a leaked object: theStringValue = [NSString stringWithUTF8String:(const char *)theXMLString]; if ( _node->type != CXMLTextKind ) xmlFree(theXMLString); } return(theStringValue); I really spent a long time and tried multiple approaches to fix this, but to no avail so far, maybe I am missing something essential? Any help is highly appreciated, thank you!

  • Custom UINavigationBar Background

    - by tigermain
    I've been trying to set up a custom background for the whole of my NavigationBar (not just the titleView) but have been struggling. I found this thread http://discussions.apple.com/thread.jspa?threadID=1649012&tstart=0 But am not sure how to implement the code snippet that is given. Is the code implemented as a new class? Also where do I instatiate the NavigationController as I have an application built with the NavigationView template so it is not done in my root controller as per the example

  • UIScrollView + UIWebView = NO scrollsToTop

    - by sniurkst
    It looks like a problem which could have simple solution, but I haven't found anything what could lead the way to it. I'm using UIWebView inside of UIScrollView and tapping on statusBar (to scroll content to top) is not working. I've made simple test application to see if it's really UIWebViews fault. And it really is. // scrolls to top on status bar tap UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); [self.view addSubview:sv]; // doesn't scroll UIScrollView *sv = [[UIScrollView alloc] init]; sv.frame = CGRectMake(0, 0, 320, 480); sv.contentSize = CGSizeMake(320, 1200); UIWebView *wv = [[UIWebView alloc] init]; wv.frame = CGRectMake(0, 0, 320, 100); [sv addSubview:wv]; [self.view addSubview:sv]; So, I think maybe there's something I could disable to make UIWebView not to mess with scrollToTop? Or some kind of workaround also would be nice. Any ideas?

  • iPhone dev: load a file from resource folder

    - by thomax
    I'm writing an iPhone app with a UIWebView which should display various html files I have in the app resource folder. In xcode my project overview, these html files are displayed like this: dirA |---> index.html |---> a1.html |---> a2.html |---> my.css |---> dirB |---> b1.html |---> b2.html |---> dirC |---> c1.html |---> c2.html These resources where added to the project as such: - Checked "Copy items into destination groups folder (if needed)". - Reference type: Default. - Text encoding: Unicode (utf-8). - Recursively create groups for any added folders. The links in my html are relative, meaning they look like this: <a href="a1.html">a2</a> <a href="a2.html">a2</a> <a href="dirB/b2.html">b2</a> <a href="dirC/c1.html">b2</a> In order to display the index.html when the app starts up, I use the following code: NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]; NSURL *url = [NSURL fileURLWithPath:path]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [webView loadRequest:request]; This works fine. Following links from the index file also works fine, as long as the html files requested are directly under dirA. If the link followed points to a file in a sub-directory, then didFailLoadWithError will catch the situation and report that the requested file does not exist. Note that [webView loadHtmlString:myHtml]; cannot be part of the solution, as I need back and forward buttons to work in my web view. So the question is: How can I follow a relative link to an html file in a sub directory within my resources? I've been all over stackoverflow and the rest of the tubes for the past few days trying to figure this one out, but nowhere have I come across the solution to this exact problem. Any insight at all would be very, very much appreciated!

  • Core data setReturnsDistinctResult not working

    - by Moze
    So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are have ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with same name but different coordinates and id. Search is implemented using NSPredicate. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch. But setReturnsDistinctResult is not working and I'm still getting all entries. Heres code: - (NSFetchRequest *)fetchRequest { if (fetchRequest == nil) { fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Stop" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setResultType:NSDictionaryResultType]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObject:[[entity propertiesByName] objectForKey:@"name"]]]; [fetchRequest setReturnsDistinctResults:YES]; DebugLog(@"fetchRequest initialized"); } return fetchRequest; } ///////////////////// - (NSFetchedResultsController *)fetchedResultsController { if (self.predicateString != nil) { self.predicate = [NSPredicate predicateWithFormat:@"name CONTAINS[cd] %@", self.predicateString]; [self.fetchRequest setPredicate:predicate]; } else { self.predicate = nil; [self.fetchRequest setPredicate:predicate]; } fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:self.fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:sectionNameKeyPath cacheName:nil]; return fetchedResultsController; } ////////////// - (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [[fetchedResultsController objectAtIndexPath:indexPath] valueForKey:@"name"]; return cell; }

  • Assigning to struct in different class

    - by 4thSpace
    I have a struct in ClassA and want to assign it to the same struct in ClassB (the two structs are the same with different names). ClassA and ClassB are view controllers. Basically, I need to pass this struct to another class. However, structs don't seem to be exposed as members, which means I can't access them. Here is ClassA's struct declared in its header file: typedef struct { NSString *startDate; NSString *endDate; NSString *classId; } selectedItemsClassAStruct; selectedItemsClassAStruct selectedItemsClassA; and the same for ClassB (just with ClassA text replaced) It doesn't appear in code hints for ClassB. I see this error if I try to access it: request for member 'selectedItemsClassBStruct' in something not a structure or union How should it be done?

  • Using plist to populate a grouped table

    - by Jack Griffiths
    Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

  • How to properly use CoreData validation & error framework ?

    - by Xav
    I've created a model in Xcode, and for various attributes I have minimum & maximum values defined and that are enforced by coreData at runtime. I'm using NSManagedObject validateValue:forKey:error to check for user input values. I was a bit disappointed to see that the localized error message is not specific, and I get a "The operation couldn't be completed. (Cocoa error 1620)" for too small values and a "The operation couldn't be completed. (Cocoa error 1610)" for too large values. It's written in the coreData documentation that "you can localize most aspects of a managed object model, including entity and property names and error messages". Unfortunately it's not very detailed on how you implement it for error messages. So How do you customize error message ? How do you localize them ? Is it possible to customize it in a way where it will mentioned the reference value ex: "Value should be lower than %@" or "Value should be higher than %@" ?

    Is it possible to set a custom URL scheme to launch my app from a link but make this a user defined setting? My app relies on a user defined server url and I would like to be able to set a URL scheme to launch my app using the users custom URL from lets say an email link. I noticed the info.plist has these references ${EXECUTABLE_NAME} can I define my own custom reference maybe?

  • Setting UITableViewCell button image values during scrolling

    - by Rob
    I am having an issue where I am trying to save whether a repeat image will show selected or not (it is created as a UIButton on a UITableViewCell created in IB). The issue is that since the cell gets re-used randomly, the image gets reset or set somewhere else after you start scrolling. I've looked all over and the advice was to setup an NSMutableArray to store the button's selection state and I am doing that in an array called checkRepeatState My question is: where do I put the if-then-else statement in the code to where it will actually change the button image based on if the checkRepeatState is set to 0 or 1 for the given cell that is coming back into view? Right now, the if-then-else statement I am using has absolutely no effect on the button image when it comes into view. I'm very confused at this point. Thank you ahead of time for any insight you can give!!! My code is as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // set up the cell static NSString *CellIdentifier = @"PlayerCell"; PlayerCell *cell = (PlayerCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { [[NSBundle mainBundle] loadNibNamed:@"PlayerNibCells" owner:self options:nil]; cell = tmpCell; self.tmpCell = nil; NSLog(@"Creating a new cell"); } // Display dark and light background in alternate rows -- see tableView:willDisplayCell:forRowAtIndexPath:. cell.useDarkBackground = (indexPath.row % 2 == 0); // Configure the data for the cell. NSDictionary *dataItem = [soundCategories objectAtIndex:indexPath.row]; UILabel *label; label = (UILabel *)[cell viewWithTag:1]; label.text = [dataItem objectForKey:@"AnimalName"]; label = (UILabel *)[cell viewWithTag:2]; label.text = [dataItem objectForKey:@"Description"]; UIImageView *img; img = (UIImageView *)[cell viewWithTag:3]; img.image = [UIImage imageNamed:[dataItem objectForKey:@"Icon"]]; NSInteger row = indexPath.row; NSNumber *checkValue = [checkRepeatState objectAtIndex:row]; NSLog(@"checkValue is %d", [checkValue intValue]); // Reusing cell; make sure it has correct image based on checkRepeatState value UIButton *repeatbutton = (UIButton *)[cell viewWithTag:4]; if ([checkValue intValue] == 1) { NSLog(@"repeatbutton is selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeatselected.png"] forState:UIControlStateSelected]; [repeatbutton setNeedsDisplay]; } else { NSLog(@"repeatbutton is NOT selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeat.png"] forState:UIControlStateNormal]; [repeatbutton setNeedsDisplay]; } cell.accessoryType = UITableViewCellAccessoryNone; return cell; }

  • Display shift when adding rows to UITableView

    - by Kamchatka
    Hello, I have a UITableView displaying an underlying NSFetchedResultsController. When the fetchedResultsController is updated, - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { is called. And the following is executed: case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:shiftedIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; The cellForRowAtIndexPath is only called for the new line (which is logical) The problem is however that all the values displayed in the rows of the table view are shifted down. The first row displays its title. The second rows displays the first row's title. The third row the second row's title etc. If I repeat that, the third row will display the second's row title, the fourth the third row's title etc. I don't understand what can happen, especially because cellForRowAtIndexPath is only called for the new line (which is logical) and not for all these lines. Additionally, if I click on these lines which have the wrong title, it opens the right document (didSelectRowAtIndexPath works correctly with the indexPath) Any clue of what could happen? Thanks!
